Dear TFL,
I hope this email finds you well. I am X and I am a geology student from UCL. I am currently doing a GIS project about London Underground, which is focusing on the air quality in London and trying to fathoming how the construction of a new tube line affecting the air quality in the area. Also I need to connect that with the geology in London. Therefore, I am wondering any chance you can support me. I am lacking of the depth(or elevation) of Elizabeth line stations. If you can provide the data as shape file , that would be very helpful. Thank you very much indeed.
